They pay me 70% from my sales Didn't you read what the Shareflare admin explained? Their system locks you at 70%, so even if you have many sales, if your download number is too high and cannot compensate them, they drop you to paper until you pass under 70%.

For example, you made 100$ sales for them total and until now you earned 80$ total. So this means you earned 80% from your sales, and you are dropped to paper until you make at least 11$ sales which puts you at about 69% so you can move to plumbum. If your sales are cheap (I have a lot that are only 0.81$ - probably one day premium by sms) then even if you make 10 sales you still can't get out of Paper status because you are still over 70% in total.

And I'm pretty sure Letitbit system is based on the same kinda logic, except it locks you at 60%. So no matter how many downloads, you practically always earn the same - if today you had many sales and few downloads your efficiency raises so you earn more in the next days even if you don't have sales until you reach your 60% maximum and then your efficiency and $/1000dl drops until you make sales again. So, if your earnings dropped to 55% because of the glitch yesterday, your efficiency will raise to compensate for the 5% losses and you will earn the lost money back in the next days. It's just how the system is.
